It will from the following description taken in connecnaturally follow that if the divided seat is emtion with the accompanying drawing, wherein ployed, my ventilating tube It should then be Figural is a top plan view of a toilet embodycomposed of two tubes which would extend 55 around to the end of each leg of the seat. The single tube I 8, or the two tubes. if the divided seat is used, may be secured to seat I! in any convenient manner. If a reasonably wide base is provided on tube I6 it may be satisfactorily glued to the seat, otherwise it can be screw fiastened thereto. The rearward ends of tube I6 are formed with a centering cone arrangement probably best illustrated in Figures 2 and 5 at l8. This provides for a positive union with the rubber bushings 20 which are formed within the base 22 of my attachment.

My attachment consists essentially in three members, the ventilating conduit, just described,

the base member 22 and the motor 2 3. Base 22 has, formed within it, two passageways as 25 and 26 which lead to the spinner of a rotary fan 28, and provide the intake to the fan. The fan following the principles of impeller type tans expels the gases drawn through conduit is and passageways 25 and 26 out through passageway 30 v into pipe 3| which may be .led to any convenient point of discharge. Impeller 28 is preferably secured directly to the armature shaft 32 of r'notor 24. In this way the bearings provided in the motor serve also as bearings for the fan, making a simple, inexpensive and compact arrangement.

My base member 22 can best be secured to the toilet by using the same bolts that support pivot l5, it being necessary only to provide through openings in base 22 to accommodate them.

It is, of course, desirable to have the fan operate only during periods when the toilet is being used. To this end I have provided that the seat I4 is normally supported, with its front end in a raised position, by resilient means as a compression spring 34 or by making duct it of rethe position or said seat.

silient rubber. Thus the normal weight of a person using the toilet will be suflicient to press it down in engagement with the toilet rim. This movement is used tooperate the electric switch 36 which is not sliown in great detail as there are many commercial switches that are adaptable for this use. The type used for burglar alarms, and the like, behind door casings, are probably the most satisfactory as a, small amount of movement of the operating button 31 serves to trip the w with a bowl and its pivoted seat spaced thereabove comprising a tubular ventilator having intake ports and mounted on the seat between said seat and bowl, resilient means for holding the 26 ventilator out of contact with the bowl, a conical. discharge head for the ventilator, abase block on the bowl and having an impeller chamber, an

outlet duct and an inlet duct for said chamber through said block, a conical nipple at one end a of the inlet duct forming a socket for said head, an impeller in said chamber, an electric motor for said impeller,- an operating circuit for the motor, and a switch in said circuit controlled by EARL s. MORRIS.
